When using HOB RDP Applet from Mac OS Sierra or High Sierra to connect to a Windows 10 v.1607 system, the connection fails with error:
"A protocol error has occurred. Errorcode: HLJWT502E. Reason: java.lang.Error: invalid device id 0xffffffff".
Windows users using the same HOBLink RDP Applet to remote to a Windows 10 v.1607 system are not affected.
Mac users may report that the issue is intermittent and that they are able to connect sometimes.
